Procedure and system for manufacturing a part made from composite material and part made from composite material obtained by means of said method

A method for manufacturing a part made from composite material, wherein the part comprises a body and one or more continuous fiber bundles arranged within said body, wherein the method comprises the stages of:

• a) obtaining a body that includes one or more tubular cavities in its interior, wherein each tubular cavity of said one or more tubular cavities extends between a first end, disposed on the outer surface of the body and which comprises an inlet orifice, and a second end, opposite to said first end;
• b) introducing resin in the liquid state and a continuous fiber bundle in the interior of at least one tubular cavity of said one or more tubular cavities through its inlet orifice, such that the input end of the continuous fiber bundle advances towards the second end of said at least one tubular cavity;
• and
• c) curing the resin until it solidifies, adhering to the body of the part and fixing the continuous fiber bundle in the interior of said at least one tubular cavity;
• wherein stage b) comprises:
• carrying out said introduction of resin in the liquid state and of said continuous fiber bundle simultaneously, performing said introduction of the continuous fiber bundle within said at least one tubular cavity exerting on the continuous fiber bundle a viscous drag force by means of the resin, applying pressure differential,
• or
• carrying out said introduction sequentially, first for the continuous fiber bundle and subsequently for the resin in the liquid state, performing said introduction of the continuous fiber bundle within said at least one tubular cavity:
• exerting a dragging force by means of a pressurized fluid along the interior of at least said tubular cavity and/or
• exerting a mechanical pushing force on the bundle of continuous fibers.

A part made from composite material, which comprises a body and at least one continuous fiber bundle arranged within said body;

• wherein said at least one continuous fiber bundle has a resin coating on its lateral surface, and wherein the part made from composite material is obtained by means of a method for manufacturing a part made from composite material, wherein the part comprises a body and one or more continuous fiber bundles arranged within said body, wherein the method comprises the stages of:
• a) obtaining a body that includes one or more tubular cavities in its interior, wherein each tubular cavity of said one or more tubular cavities extends between a first end, disposed on the outer surface of the body and which comprises an inlet orifice, and a second end, opposite to said first end;

• or
• carrying out said introduction sequentially, first for the continuous fiber bundle (208) and subsequently for the resin in the liquid state, performing said introduction of the continuous fiber bundle within said at least one tubular cavity:
• exerting a dragging force by means of a pressurized fluid along the interior of at least said tubular cavity and/or
• exerting a mechanical pushing force on the bundle of continuous fibers.
